Integrating in
Dream'lineTM
the powerful
proprietary
technologies,
EvosightTM and L-ShufflingTM
,
Proteus offers you a outstanding opportunity to
develop tailor-made proteins
via unique and
flexible services.
Rapidly evaluate in parallel a very large panel of
cell-based and cell-free expression systems
and conditions
for your genes.
Obtain proteins in
scaleable production system
from research scale toward process development.
Dramatic 50-fold improvement of the activity of a protein using a combination of
EvoSightTM and L-ShufflingTM. The figure shows the actual distribution of the activity
of the clones generated by the third round of L-ShufflingTM compared with the
starting enzyme (wild type : "WT"). Most clones exhibit an activity higher than the
original WT enzyme.
